MET HOD FOB WASHING PULP.

Application filed September 17, 1917, Serial No. 191,842. Renewed July 28, 1923.

To all whom it may concern:

a citizen of the United States, and a resident of Perkirisville, in the county of Windsor and State of Vermont, have invented certain new and useful Improvements in Methods for Washing Pulp, of which the following is a specification.

This invention relates broadly to washing apparatus, and more specifical to a pulp washing device adapted particularly for.the use of paper manufacturers in rendering used or inked paper suitable for re-use.

The principal object of the present invention is to provide an improved method and apparatus for washing pulp, which apparatus may be operated continuously, the waste or dirty water used in washing being gradually thrown off so that it is not ground into the paper fibers.

' A further object of the present invention is to provide a Washing apparatus comprising a series of tubular washers through which the pulp is continuously passed, and so constructing the same that a considerable quantity of water may be kept therein to assist in the agitating, washing and flowing of the pulp.

Still another'object of the present invention is to provide a series of tubes of the above nature having therein means for continuously agitating, washing and feeding the pulp.

A still further object of the present invention is to provide in such a washer means for regulating the amount of pulp contained therein.

These and other objects, together with their attendant advantages will be apparent as the invention becomes better understood by reference to the accompanying specification, and drawings forming a part thereof, throughout the several views of which like characters of reference have been used to indicate like parts.

In-the drawings, Figure 1 is aside view of my improved washing apparatus.

Fi re 2 is a cross sectional v1ew illustrating the relative positions of the tubular washers.

Figure 3 is a detail View showing the adjustable dam or gate for regulating the quantity of pulp in the washer.-

Figure 4 is an enlarged view of a modified form of washer.

Figure 5 is a detail view of an adjustable most entirel mounting for the a 'tatin or ro ellin Be it known that I, Or'ro-C. Wrunsroon, g1 g p p g them objectionable for many purposes. With the present invention this objection is aleliminated inasmuch as the waste water is thrown off as it becomes dirty so that the fibers are continually subjected to the-action of clean washing fluid.

Referring moreparticularly to the drawings, my improved washer preferably comprises a plurality of tubular members 1 which may be of any desired length depending upon the type of pulp to be washed, and the number of which may be varied at will depending upon the particular use of the machine. Each of the tubes preferably comprises an imperforate lower portion 2 in the form ofa half tube, and an upper perforate portion 4 secured to the imperforate portion by means of the flanges 5 formed thereon, and the co-operatin locking plates 6. The perforate portion 0 the tube may be constructed of ordinary heavy screening, or of sheet metal having a plurality of openings suitably punched therethrough. In order,

'to construct the apparatus so that the smallest possible amount of room is utilized in installing the same, the tubes are preferably constructed in comparatively short sections which may be connected by elbows 7 so that the occupy the desired positions.

' While the el ows are indicated as being of solid material throughout, they may be constructed with a perforate portion in the same manner as the main body of the tubes in case such a construction is deemed advisable. The pulp to be washed is fed to a chest 8 havingthe usual overflow'connection, and in communication with the tubes through a regulating valve 9 of any desired construction.

Extendin longitudinally of the tubes, and projectlng beyond the connecting elbows is a plurality of hollow shafts 10 journalled in suitable stufling boxes 11 secured to the elbows. The shafts are adapted to be rotated by means of gears or the like 12 splined thereto in any well known manner, and

In the -drawings,.wherein forthe purpose of illustrationis shown a preferred embodi mentrof my invention, the numeral 1 designates acasing having sidewalls 2 and 3, end walls 4? and 5, bottom wall 6 and open top 7, the casing is further provided with.- legs ,8 that-Q31 6;- positioned at p the iourcor-" "ners of the bottom 6, and handles 9 that are carried-bythe" oppositersidc walls to furnish means for carrying the ash sifter wall 2 is provided with a door 10 that is secured to the said wall by 'means of the hinges 11 and is further provided with a' catch 12 for retaining the door in a closed ,position. The end wall 4 is provided with a door 13 that is hingedly connected to the i from place to place as desired. a The side casing by the hinges 1e and is further providedwith acatch member 15 for retaining the door 111 a closed position. The open top 7 is providedwith a cover 16; that is con-' nected to the casing by means of the hinges: 17 and is further-provided with a handle knob 18 to. facilitate. the opening of the same when ashes-are .to be placed within" the-casing.

Referring more particularly to Figures 12 and 3 there is shown an ash-receiving hopper member 19. that is formed integrally with the said casing and having walls that slope towards the opening 20 formed by the lower edgcsthereot: The passage of ashes through the opening 20 is co'ntrolledby the flap valve 21 having a supporting rod 22 that is pivotally secured to the under face of the hopper member by the. eye-bolts 23.

The said flap valve'is normally held in a closed position by means of aspring memher. that consistsofthe valve engaging portion 24 having its ends coiled around the: supporting rod 22 as at 25 to terminate in resiiient arms 26 that are adapted to' press against the under surface of the hopper member for retaining the supporting portion -2etagainstthe nnder surface of the This flap valve is further providedwith a wire member 27 that is seing portion 24 to form a depending arm 28. having an eye29' that is formed thereon cured to the supporting rod 22 and extends f transversely to be bent around the support-- to provide a connectionior actuating mechr anism that will be presently described.

The siftingmember, as best shown in Fig.

3, embodies a rectangular frame'consisting of sidewalls 30 and one'end wall 31, the opposits end being left open for discharging the unburnt coalsiromthe same after the ash dust has been separated therefrom, The bottom or the sitting member consists of a ;.transverse end board 32 that 1s secured to the lower edges at the open end ofthe side wallsBO and adapted-for strengthening thesame and is provided with a depending deflector-plate 33 that isadapted to direct the coal dnst, aassing through the wire sifting screen 34, ,into the receptacle 35 placed therebelow. The forward end of the sifting v member is supported by the angular rod 36 that is pivotally secured as at 37 to the side walls of the casing, and to the end board 32 by the straps 38. The inner end of the sifting member is vertically adjustably supported by means of the longitudinally extending arms 39 that are secured to the side wallsSO as at 10 and have flexible cords 4-1, that are secured to the outer ends of the arms 39 and extend upwardly to be wound around the sheaves 42that-are carried by the horizontal shaft 1-3. Thisshaft 43 is journaled at oncend within the bearing member 14:, carried by the side wall 3, and at its opposite end is journaled'in the bearing member carried by the side wall 2 and projects outwardly therefrom for carrying the ratchet wheel 46 and operating wheel 4:7. 7 ried by theside wall 2 and is adapted'to engage the teeth of the ratchet wheel to retain .the sifting member in its adjusted position.

Positioned beneath the open end of the sifting member are deflector plates a9 that are provided to direct the unburnt coals into the receptacle 50 positioned 'therebelow. It is to be understood that the receptacle 50 may be removed from the casing through the door 10 carried by the side wall 2 and that the receptacle 85 may be removed from the casing through the door 13 carried by the end wall 4. These two receptacles are further provided with finger gripping apertures 51 to facilitate in removing the same from the casing. The bottom wall 6 is pro The actuating means for the sifting memher and the flap valve 21 embodies a relatively large gear 52 that is carried by the shaft 53 that is journaled in the opposite sides of the casing 1 and provided with an operating crank handle 54 as shown in Figures 1 and 2. tending lugs 55 and journaled therein, is 'a crank shaft 56 that carries the pinion 57 secured'thereto, which is constantly in mesh with the larger gear 52. A crank portion 58 is formed on the crank shaft 56 and is loosely connected to the substantially V- shaped member 59 that extends forwardly to be connected to the side walls 30 of the sifting member by the transverse rod 60. A connection rod 61 1s ournaled upon the transverse rod as at 62 and is connected at its free end to the eye 29 carried by the per member 19 through the opening 7 of. V

A spring pressed pawl a8 is car-' Secured to the laterally exthe casing and the cover 16 is moved to close the opening to prevent-ash dust from leaving the hopper. The sifting member is adjustedto its proper inclined position by the operating wheel 47 to regulate the speed of travel of the ashes over the sifting screen 84. The crank handle 54 is operated to ro tate the gear 52 to rotate the crank shaft 56 through the medium of the pinion 57, the

crank portion 58, being connected with the sifting member through the substantiallyV- shaped member 59, will cause the said sifting member to reciprocate, from its full line position to its dotted line position as shown in Fig. 3, upon its forward supporting angular rod 36 and rear end supporting cords ll to cause the ash dust to be sifted through the screen 34: into the receptacle 35Vand to feed the unburnt coals forwardly to the open end of the member into the said recep- I tacle 50. The connection rod 61, being connected to the sifting member by the horizon tal rod 60, will actuate the flap valve 21 in unison with the sifting member, to cause a charge of unsifted ashes to be deposited from the hopper member 19 into the inner end of the sifting member.

It will be apparent that regulating the feeding of the unsifted ashes into the sift- 7 ing member will prevent overloading of the described the invention, 1
